On January 31, 2025 at 22:16 UTC, a magnitude 4.4 intermediate depth earthquake struck 33 km S of Makurazaki, Japan, at a depth of 153.6 km and coordinates 30.9646°, 130.3362°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
